QUICK!! Blazer and Jimmy Diamond Edition compatablility ?'s QUICK!

I NEED ANSWERS ASAP!!!

I was lookin at a set of nerf bars (steps) and the brush guard for the Diamond Edition Jimmy that someone is selling.
Will they bolt right up to my 99 Blazer?
Are the front bumpers the same?
Where does it bolt up to?
And am i going to have problems because i have the oil filter that is right in front?

Thanks!

First off, what is the year of the diamond edition?
